Product details
Overview
OPA2354AIDDAG3 from Texas Instruments is a dual-channel, rail-to-rail input/output, 250-MHz unity-gain stable CMOS operational amplifier optimized for high-speed video, photodiode transimpedance, and A/D converter buffering. It delivers 150 V/µs slew rate, 6.5 nV/√Hz input voltage noise, ±100 mA output current per channel, and operates from 2.5 V to 5.5 V supply. It is used in ultrasound front-ends and optical networking laser bias control.
For engineers reviewing the OPA2354AIDDAG3 datasheet, OPA2354AIDDAG3 pinout, OPA2354AIDDAG3 application, or OPA2354AIDDAG3 equivalent, key selection criteria include its 100-MHz gain-bandwidth product, −40°C to +125°C extended temperature range, 0.02% differential gain error for composite video, channel-to-channel crosstalk of −100 dB at 5 MHz, and compatibility with single-supply 3.3-V or 5-V systems requiring fast settling (30 ns to 0.1%).
Technical Context
The OPA2354AIDDAG3 employs a complementary CMOS input stage enabling rail-to-rail input operation beyond the supply rails by ±100 mV, paired with a Class AB output stage delivering rail-to-rail swing within 100 mV of rails under 1-kΩ load. Its voltage-feedback architecture supports unity-gain stability without external compensation.
It integrates thermal shutdown activation at 160°C and recovery at 140°C, supports dual-supply (±1.25 V to ±2.75 V) or single-supply operation, and features independent channel circuitry ensuring minimal interaction-critical for dual-channel signal paths in RGB video drivers or differential sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250 MHz - enables stable unity-gain buffer configurations for wideband signals up to 250 MHz without peaking or oscillation |
| Slew Rate | 150 V/µs - supports clean 2-V step response in ≤11 ns, critical for fast pulse conditioning and DAC output amplification |
| Input Voltage Noise | 6.5 nV/√Hz at 1 MHz - low-noise performance suitable for photodiode transimpedance amps and precision analog front-ends |
| Output Current | ±100 mA per channel - drives 75-Ω back-terminated video cables or laser diodes directly without external buffers |
| Supply Range | 2.5 V to 5.5 V - compatible with both 3.3-V and 5-V industrial, medical, and communications systems |
| Differential Gain/Phase | 0.02% / 0.09° - meets NTSC/PAL video fidelity requirements for broadcast-quality RGB or composite video line drivers |
| Channel Crosstalk | −100 dB at 5 MHz - ensures isolation between channels in dual-path applications like stereo ultrasound receive or dual ADC inputs |
Pinout & Package
OPA2354AIDDAG3 is housed in an 8-pin VSSOP package (DGK suffix), measuring 3.00 mm × 3.00 mm, with exposed thermal pad connected to V− for enhanced power dissipation. The package supports high-density PCB layouts while maintaining thermal performance (RθJA = 175.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±100 mA; requires local 0.1-µF bypass capacitor near V+ and V− pins |
| 2 | –IN A | Inverting input, channel A - high-impedance CMOS node; sensitive to layout-induced parasitics above 10 MHz |
| 3 | +IN A | Noninverting input, channel A - accepts common-mode voltages from (V−) −0.1 V to (V+) +0.1 V |
| 4 | V− | Negative supply terminal - must be connected to ground or negative rail; PowerPAD tied to this pin improves thermal resistance |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; enables dual independent gain stages on one die |
| 6 | –IN B | Inverting input, channel B - identical electrical characteristics to pin 2; no internal coupling to channel A |
| 7 | OUT B | Amplifier B output - fully independent output stage; supports simultaneous high-speed operation with channel A |
| 8 | V+ | Positive supply terminal - supplies both channels; decoupling required within 2 mm of pin for >100-MHz stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail I/O | Input common-mode range extends 100 mV beyond supplies; output swings to within 100 mV of rails at 1-kΩ load - maximizes dynamic range in low-voltage 3.3-V systems |
| Thermal Shutdown | Activates at 160°C junction temperature and resets at 140°C - protects against sustained overload in laser driver or video line driver applications |
| Low Input Bias Current | 3 pA typical - minimizes offset drift in high-impedance photodiode transimpedance circuits and precision sensor interfaces |
| High Output Drive | ±100 mA continuous per channel - eliminates need for external buffer stages when driving 75-Ω video lines or moderate-current laser diodes |
| Extended Temperature Range | Specified from −40°C to +125°C - qualified for automotive ADAS imaging modules, industrial ultrasound probes, and outdoor optical transceivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2354AIDGKR | Same silicon, 8-pin VSSOP package but tape-and-reel packaging (DGKR vs DDDAG3); identical electrical specs and pinout | No functional difference; selected for automated SMT assembly where reel format is required | Choose OPA2354AIDGKR for high-volume pick-and-place production; OPA2354AIDDAG3 is same device in cut-tape format |
| OPA2355AIDGKT | 200-MHz GBW, rail-to-rail output only (not input), lower quiescent current (3.5 mA vs 4.9 mA), no thermal shutdown | Not suitable for rail-to-rail input sensing or overtemperature-prone laser bias circuits; better for battery-powered low-power apps | Select OPA2355AIDGKT only if input rail-to-rail capability and thermal protection are not required and power budget is constrained |
Compared with OPA2354AIDDAG3, OPA2354AIDGKR offers identical performance in reel format for volume manufacturing, while OPA2355AIDGKT trades input rail-to-rail operation and thermal safety for lower power-making it unsuitable as a drop-in replacement where those features are essential.

FAQ
What is the maximum operating temperature range for the OPA2354AIDDAG3?
The OPA2354AIDDAG3 is specified over an extended industrial temperature range of −40°C to +125°C. Its thermal shutdown activates at 160°C junction temperature and resets at 140°C, providing robust protection in high-ambient environments such as automotive ADAS modules or enclosed medical equipment housings. This specification is confirmed in Section 7.3 and 7.7 of the SBOS233G datasheet.
Does the OPA2354AIDDAG3 support single-supply operation?
Yes, the OPA2354AIDDAG3 supports true single-supply operation from 2.5 V to 5.5 V. Its rail-to-rail input stage accepts common-mode voltages from (V−) −0.1 V to (V+) +0.1 V, and its output swings within 100 mV of both rails under 1-kΩ load-enabling use in 3.3-V or 5-V systems without level-shifting circuitry. This is detailed in Sections 8.3.2 and 8.3.3 of the datasheet.
What is the channel-to-channel crosstalk performance of the OPA2354AIDDAG3?
The OPA2354AIDDAG3 achieves −100 dB channel-to-channel crosstalk at 5 MHz, as measured in Section 7.7 of the SBOS233G datasheet. This low coupling results from completely independent circuitry per channel and is critical in dual-path applications like stereo ultrasound receivers or dual ADC input buffering where signal integrity between channels must be preserved.
Can the OPA2354AIDDAG3 drive a 75-Ω video cable directly?
Yes, the OPA2354AIDDAG3 is explicitly characterized for 75-Ω back-terminated video cable driving, with 0.02% differential gain error and 0.09° differential phase error under NTSC conditions (Section 1, Features and Figure 18). Its ±100 mA output current and rail-to-rail output swing enable direct connection without external buffers-verified in Figure 32 and Section 8.3.5 of the datasheet.
Is thermal shutdown included in the OPA2354AIDDAG3?
Yes, the OPA2354AIDDAG3 integrates on-chip thermal shutdown that activates at 160°C junction temperature and resets automatically when the die cools to 140°C. This protection is documented in Section 7.7 (Power Supply table) and Section 8.3.4 of the SBOS233G datasheet, and is essential for reliability in laser diode bias or high-current video driver applications.
